plays an importantrole in vascular plants wood formation. The objectives

of this research were

tostudy teakwood anatomy

and

dendroclimatology potentiality,tocharacterizeCAD

gene andexpression profiles in secondary wood tissue of teak

and finallytorelate expression withteak wood anatomy.Consequently,degenerate primers of different genus were used toidentify theTgCAD1,PCR products were sequenced,analyzed, it wasestablishedaminoacidsimilarities andTgCAD1
